That chart doesn't mean as much when you don't list the exact bullet you will be using. There are lots of pointed/boat-tailed bullets that look good on paper that I would never use on an elk.
And ft/lbs are a good starting point, but they are just a mathmatical formula that will generally give the better look on paper to faster bullets.
That said, a PREMIUM 139 gr bullet is an elk killer IF, as several have said, you put it in the boiler room. And sure, the 243 has taken plenty of elk, but not at 400 yards.
However, ft/lbs don't mean much when you hit a bone. I will take the 160 gr slower bullet EVERY time if I happen to hit a shoulder bone even though it has lower ft/lbs.
Flat is good too, but out to reasonable shooting distances for the majority of us (300-400 yards), the difference is not that big on an elk sized animal.
